It is not recommended to stick tiles or apply putty with strong rigidity on it.

　　3、轻质抹灰石膏：

　　3. Lightweight plastering gypsum:

　　作为一种新型内墙抹灰材料，轻质抹灰石膏将完全代替传统水泥砂浆，这从发达国家轻质抹灰石膏在室内墙面找平中占主导地位可窥见一斑。在美国、德国、法国、西班牙、土耳其，轻质抹灰石膏占90%份额，水泥砂浆已不到10%；在英国，轻质内墙抹灰石膏占椐96%份额。

　　As a new type of interior wall plastering material, lightweight plastering gypsum will completely replace traditional cement mortar, which can be seen from the dominant position of lightweight plastering gypsum in indoor wall leveling in developed countries. In the United States, Germany, France, Spain and Türkiye, light plaster gypsum accounts for 90% of the total, while cement mortar accounts for less than 10%; In the UK, lightweight interior plastering gypsum accounts for 96% of the market share.

　　适用范围：除卫生间，厨房之外、适用于各种砖墙、混凝土墙、砌块墙、水泥墙（板）、现浇混凝土墙、装配式内隔墙板的内墙面抹灰找平及修补。

　　Scope of application: In addition to bathrooms and kitchens, it is suitable for plastering, leveling, and repairing various types of brick walls, concrete walls, block walls, cement walls (slabs), cast-in-place concrete walls, and prefabricated interior partition walls.

　　轻质抹灰石膏作为一种新型内墙抹灰石膏，除了上述环保、保温特点外，轻质抹灰石膏还具有以下特点：

　　Lightweight plastering gypsum, as a new type of interior wall plastering gypsum, has the following characteristics in addition to the environmental protection and insulation features mentioned above:

　　高效：轻质抹灰石膏作业面针对下一道腻子工序的间隔周期是很短的，效率远高于传统砂浆抹灰。从而为业主和总包节省相当可观的时间和费用。

　　Efficient: The interval between the lightweight plastering gypsum work surface and the next putty process is very short, and the efficiency is much higher than traditional mortar plastering. This saves considerable time and costs for both the owners and the general contractor.

　　重量轻、施工面积大、能耗低：同重量下，轻质抹灰石膏施工面积是普通抹灰石膏的1.6-1.8倍, 是传统商品水泥抹灰砂浆粉刷面积的2倍多。可以较大地节省用量、运力及费用和生产能耗，从而降低总体造价。同时还可以降低建筑负载总量。

　　Lightweight, large construction area, and low energy consumption: Under the same weight, the construction area of lightweight plastering gypsum is 1.6-1.8 times that of ordinary plastering gypsum, and more than twice that of traditional commodity cement plastering mortar. It can significantly save on usage, transportation capacity, costs, and production energy consumption, thereby reducing overall costs. At the same time, it can also reduce the total load of the building.

　　施工方便：轻质抹灰石膏既可以手工抹灰施工，且工人施工相对普通抹灰石膏更省力，效率更高。也可以通过机器喷涂的方式进行（效率提高约1倍），同时也是冲筋工艺的首选材料。轻质抹灰石膏具有良好的抗裂性，适合墙面进行薄抹灰，不同的施工场所对它的厚度有不同的要求。墙体施工厚度为5~20mm，最小厚度不小于5mm，顶面抹灰总厚度应小于10mm。一般来说在家装工地施工中，它的厚度大多在10mm左右;有的工地施工则是做15mm。

　　Convenient construction: Lightweight plastering gypsum can be manually applied, and workers are more labor-saving and efficient in construction compared to ordinary plastering gypsum. It can also be done by machine spraying (increasing efficiency by about 1 times), and it is also the preferred material for the punching process. Lightweight plastering gypsum has good crack resistance and is suitable for thin plastering on walls. Different construction sites have different requirements for its thickness. The thickness of wall construction is 5-20mm, with a minimum thickness of not less than 5mm, and the total thickness of top plastering should be less than 10mm. Generally speaking, in home decoration construction sites, its thickness is mostly around 10mm; Some construction sites require a thickness of 15mm.

　　上墙效果好：轻质抹灰石膏材料构成都比较细腻，上墙效果好。

　　Good wall effect: The lightweight plastering gypsum material composition is relatively delicate, and the wall effect is good.

　　抹灰石膏和轻质抹灰石膏，

　　Plastering gypsum and lightweight plastering gypsum,

　　功能相似，那如何选择呢？

　　How to choose if the functions are similar?

　　我们通常所说的抹灰石膏，一般是重质石膏，而轻质抹灰石膏通常称之为轻抹。

　　The plastering gypsum we usually refer to is usually heavy gypsum, while lightweight plastering gypsum is usually called light plaster.

　　骨料不同

　　Different aggregates

　　重质石膏和轻质石膏两者骨料不一样，重质石膏骨料是沙子，轻质石膏是玻化微珠。玻化微珠作轻质填充骨料有绝热、防火、吸音等优点。在建材行业中，用玻化微珠作为轻质骨料，可提高砂浆的和易流动性和自抗强度，减少材性收缩率，提高产品综合性能，降低综合生产成本。同时玻化微珠相较沙子还可以因为表面玻化形成一定的颗粒强度，而具有耐老化耐候性强和优异的绝热、防火、吸音等性能。

　　Heavy gypsum and light gypsum have different aggregates. Heavy gypsum aggregates are sand, while light gypsum aggregates are vitrified microbeads. Vitrified microbeads as lightweight filling aggregates have advantages such as thermal insulation, fire resistance, and sound absorption. In the building materials industry, using vitrified microbeads as lightweight aggregates can improve the workability and self strength of mortar, reduce material shrinkage, enhance product performance, and reduce overall production costs. At the same time, compared to sand, vitrified microbeads can also form a certain particle strength due to surface vitrification, and have strong aging and weather resistance, as well as excellent insulation, fire resistance, sound absorption and other properties.

　　石膏含量不同

　　Gypsum content varies

　　轻质抹灰石膏要求石膏粉含量≥75%，重质抹灰石膏要求石膏粉含量≥35%。

　　Lightweight plastering gypsum requires a gypsum powder content of ≥ 75%, while heavy plastering gypsum requires a gypsum powder content of ≥ 35%.

　　技术性能不同

　　Different technical performance

　　1、密度不同；轻质抹灰石膏密度≤1000kg/m3，重质抹灰石膏密度＞1000kg/m3。

　　1. Different densities; The density of lightweight plastering gypsum is ≤ 1000kg/m3, and the density of heavy plastering gypsum is>1000kg/m3.

　　2、保水率（%）；轻质抹灰石膏保水率≥ 60%，重质抹灰石膏保水率≥ 75%。

　　2. Water retention rate (%); The water retention rate of lightweight plastering gypsum is ≥ 60%, and the water retention rate of heavy-duty plastering gypsum is ≥ 75%.

　　3、拉伸粘结强度；轻质抹灰石膏拉伸粘结强度≥0.3Mpa，重质抹灰石膏拉伸粘结强度≥0.4Mpa。

　　3. Tensile bonding strength; The tensile bonding strength of lightweight plastering gypsum is ≥ 0.3Mpa, and the tensile bonding strength of heavy plastering gypsum is ≥ 0.4Mpa.

　　4、抗压强度；轻质抹灰石膏抗压强度≥1.5Mpa，重质抹灰石膏抗压强度≥4.0Mpa。

　　4. Compressive strength; The compressive strength of lightweight plastering gypsum is ≥ 1.5Mpa, and the compressive strength of heavy plastering gypsum is ≥ 4.0Mpa.

　　5、抗折强度；轻质抹灰石膏抗折强度≥1.0Mpa，重质抹灰石膏抗折强度≥2.0Mpa。

　　5. Flexural strength; The flexural strength of lightweight plastering gypsum is ≥ 1.0Mpa, and the flexural strength of heavy-duty plastering gypsum is ≥ 2.0Mpa.

　　轻质抹灰石膏具有容重小，施工便捷，好运输，遇水不化，成本低，保温性能优良，强度适中，能够机械喷涂等种种特点，是淘汰重质粉刷石膏后的又一升级换代产品。给开发商和施工单位带来了福音，给住户带来了更加舒适的环境。轻质抹灰石膏与市场上相比，每吨可出面积130㎡/公分，是重质粉刷石膏的3倍，大大提高了施工的效率和运输成本。

　　Lightweight plastering gypsum has various characteristics such as low bulk density, convenient construction, easy transportation, non hydration when in contact with water, low cost, excellent insulation performance, moderate strength, and the ability to be mechanically sprayed. It is another upgraded product after eliminating heavy plastering gypsum. Bringing good news to developers and construction units, and providing residents with a more comfortable environment. Compared with the market, lightweight plastering gypsum can produce an area of 130 square meters per ton, which is three times that of heavy plastering gypsum, greatly improving construction efficiency and transportation costs.

　　重质粉刷石膏主要以沙子为主，轻质抹灰石膏主要以石膏为主，这是从重与轻当中的直观理解，在施工厚度方面重质石膏单批次0.6cm左右，施工过厚容易出现下坠，开裂等情况，轻质石膏就不一样了，单次可以达到1cm左右，同时轻质石膏比较粘稠不会出现空鼓、下坠等情况。

　　Heavy plastering gypsum is mainly composed of sand, while lightweight plastering gypsum is mainly composed of gypsum. This is an intuitive understanding of the difference between heavy and light. In terms of construction thickness, heavy gypsum can be used in a single batch of about 0.6cm. If the construction thickness is too thick, it is easy to fall or crack, while lightweight gypsum is different. A single batch can reach about 1cm, and lightweight gypsum is relatively viscous and will not cause hollowing or falling.
